Located in King County, Washington, Big Heart Falls is a waterfall. It is part of Alpine Lakes Wilderness. The nearest town is Tanner, about 34 km (21 mi) away (Big Heart Falls lies ENE of town).
Big Heart Falls is a waterfall on the outlet stream of Big Heart Lake, which eventually flows into the Skykomish River, in King County, Washington. It is located between the outlet of Big Heart Lake and the inlet of Delta Lake. The falls are said to drop approximately 1,268 feet (386 m). The falls have two stages separated by a series of cascades. Each of the main tiers is approximately 600 feet (180 m) tall. It has an average volume of 80 cubic feet per second (2.3 m3/s). The waterfall is also very difficult to access. For one to reach it, one must circumnavigate Delta Lake and cross Copper Creek, a large glacial stream. The waterfall is located less than a quarter mile from Angeline Falls, and shares the same cliff with it. Big Heart Lake was presumably named because of its roughly heart shaped surface.From the Wikipedia article “Big Heart Falls”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Waterfalls photograph best in soft, even light: overcast days, deep shade, or the hour after sunrise before direct sun hits the water. Bright sun on white water blows highlights and adds harsh contrast.

Local time (America/Los Angeles), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Big Heart Falls, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 1.8 hours on a moonless night), and the core peaks around 14° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.26 mag/arcsec². Aurora needs roughly Kp 4.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 36% average cloud cover) and January as the cloudiest (76%). August is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this waterfall
- A circular polarizer cuts glare on wet rocks and leaves and deepens greens — rotate it while watching the rocks, not the sky.
- Spring snowmelt and the days after heavy rain give the strongest flow; late summer flow can drop to a trickle.
- Look for a foreground: a mossy boulder, a fallen log or the creek's leading lines make a stronger frame than the falls alone.
- Keep a microfiber cloth handy — spray drifts onto the lens, especially at the plunge pool.
- Bracket shutter speeds: 1/8 s, 1/2 s and 2 s give very different water textures and you can choose later.
- Check road and trail conditions with the managing agency before you go.
Season: Peak flow is usually in late spring; autumn adds color around the falls, and winter can bring ice formations at colder locations.
Suggested gear: Tripod, Circular polarizer, 3–6 stop ND filter, Lens cloth, Waterproof footwear. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Drones: Drones may not take off from or land in federally designated wilderness, where mechanized equipment is prohibited under the Wilderness Act.
